BACKGROUND: The optimal duration of dual antiplatelet therapy (DAPT) after drug-eluting stent (DES) implantation remains undetermined, especially for those at high risk of cardiac events postprocedure. OBJECTIVES: This study was aimed to investigate the impact of 6 versus 12 months of DAPT after DES implantation based on risk stratification with the residual SYNTAX score (rSS). METHODS: A total of 2737 patients in the I-LOVE-IT 2 trial were grouped according to rSS status (low rSS [rSS = 0, n = 1474] versus high rSS [rSS > 0, n = 1263]) and DAPT duration (6 months vs...

The Addendum Guidelines for the Prevention of Peanut Allergy in the United States-Report of the NIAID-Sponsored Expert Panel were developed to build on previous food allergy guidelines after several key studies demonstrated the benefit of early introduction of allergenic foods. These landmark studies including the Learning Early about Peanut (LEAP), LEAP-On and Enquiring about Tolerance trials created a paradigm shift in food allergy prevention. The "take home" messages of this guideline include that peanut should be introduced early in the first year of life, and for the majority of infants, peanut can be introduced at home...

BACKGROUND: Perioperative care for patients undergoing carotid endarterectomy (CEA) often presents a challenge to the anesthesia provider, as this patient group commonly suffers from a wide range of comorbidities. Although clinical trials could not demonstrate a significant benefit associated with regional anesthesia for outcomes such as insult, cardiac infarction or mortality, many authors concur that regional anesthetic techniques might be preferential in specific patient populations for this type of surgery...

Endpoints related to tumor progression are commonly used in clinical trials of novel therapeutic agents for neuroendocrine tumors (NETs). Whether improved tumor control translates into improved overall survival (OS), however, is uncertain. We assessed associations between tumor progression endpoints and OS in observational cohorts of patients with advanced neuroendocrine tumors treated with somatostatin analogs or with everolimus. We identified 440 patients with advanced NET who had received treatment with single-agent somatostatin analogs and 109 patients treated with everolimus, all of whom were treated at our institution and were evaluable for both tumor progression and survival...

Animals use cues from their environment to orient in space and to navigate their surroundings. Geometry is a cue whose informational content may originate from the metric properties of a given environment, and its use has been demonstrated in the laboratory in nearly every species of animal tested. However, it is not clear whether geometric information, used by animals typically tested in small, rectangular boxes, is directly relevant to animals in their natural environment. Here we present the first data that confirm the use of geometric cues by a free-living animal in the wild...

BACKGROUND: Food allergy is an important public health problem because it affects children and adults, can be severe and even life-threatening, and may be increasing in prevalence. Beginning in 2008, the National Institute of Allergy and Infectious Diseases, working with other organizations and advocacy groups, led the development of the first clinical guidelines for the diagnosis and management of food allergy. A recent landmark clinical trial and other emerging data suggest that peanut allergy can be prevented through introduction of peanut-containing foods beginning in infancy...

The past decade has seen major advances in gene-based therapies, many of which show promise for translation to human disease. At the forefront of research in this field is ocular disease, as the eye lends itself to gene-based interventions due to its accessibility, relatively immune-privileged status, and ability to be non-invasively monitored. A landmark study in 2001 demonstrating successful gene therapy in a large-animal model for Leber congenital amaurosis set the stage for translation of these strategies from the bench to the bedside...

BACKGROUND AND PURPOSE: The landmark National Institute of Neurological Disorders and Stroke (NINDS) tissue plasminogen activator (tPA) trial established the effectiveness and dosing of intravenous tPA for acute ischemic stroke (AIS) at .9 mg/kg with a maximum dose of 90 mg. Since the publication of the NINDS trial in 1995, there has been a drastic increase in the amount of obesity and the average weight of adults in the United States, which has caused an increase in the number of patients receiving 90 mg of alteplase for AIS...

New oral anticoagulants (NOAC) serve as alternatives for patients currently using warfarin for the prevention and treatment of venous thromboembolic (VTE) disease. This article provides a brief summary of the clinical use of these drugs as well as a review of the landmark clinical trials which evaluated described their safety and efficacy. As more data becomes available, a fundamental understanding of these medications will be vital to cardiovascular practitioners managing patients with VTE.

Hemispatial neglect is a severe cognitive condition frequently observed after a stroke, associated with unawareness of one side of space, disability and poor long-term outcome. Visuomotor feedback training (VFT) is a neglect rehabilitation technique that involves a simple, inexpensive and feasible training of grasping-to-lift rods at the centre. We compared the immediate and long-term effects of VFT vs. a control training when delivered in a home-based setting. Twenty participants were randomly allocated to an intervention (who received VFT) or a control group (n = 10 each)...

BACKGROUND: To assess clinical outcomes of patients needing short dual antiplatelet therapy (S-DAPT) after PCI with Cre8 polymer-free amphilimus eluting-stent (AES). The Cre8-AES with pure i-Carbofilm coating was supposed to induce faster stent endothelialization and reduce device thrombogenicity. METHODS: We performed a sub-analysis of unrestricted consecutive patients treated with Cre8-AES between August 2011 and January 2015. Two groups were formed: 1) patients discharged with S-DAPT (≤3-month), because of high bleeding risk or attending urgent non-cardiac surgery; and 2) patients discharged with Recommended DAPT duration (R-DAPT; ≥6-month)...

The efficacy of the sodium-glucose cotransporter 2 (SGLT2) inhibitors canagliflozin, dapagliflozin, and empagliflozin in reducing hyperglycemia in patients with type 2 diabetes is well documented. In addition, positive effects have been observed with these agents on nonglycemic variables, such as reductions in body weight and blood pressure, which may confer additional health benefits. SGLT2 inhibitors are also associated with evidence of renal-protecting benefits. Furthermore, during the landmark Empagliflozin, Cardiovascular Outcomes, and Mortality in Type 2 Diabetes (EMPA-REG OUTCOME) trial, a substantial reduction in major adverse cardiovascular outcomes was demonstrated with empagliflozin therapy...

BACKGROUND: The lower superior vena cava (SVC), near its junction with the right atrium (RA), is considered the ideal location for the central venous catheter tip to ensure proper function and prevent injuries. We determined catheter insertion depth with a new formula using the sternoclavicular joint and the carina as radiological landmarks, with a 1.5 cm safety margin. The accuracy of tip positioning with the radiological landmark-based technique (R) and Peres' formula (P) was compared using transoesophageal echocardiography...

Brain metastases are highly-evolved manifestations of breast cancer arising in a unique microenvironment, giving them exceptional adaptability in the face of new extrinsic pressures. The incidence is rising in line with population ageing, and use of newer therapies that stabilise metastatic disease burden with variable efficacy throughout the body. Historically, there has been a widely-held view that brain metastases do not respond to circulating therapeutics because the blood-brain-barrier (BBB) restricts their uptake...

The mechanism of action of pertuzumab, a recombinant anti-HER2 humanized monoclonal antibody, is complementary to trastuzumab's. On 8 June 2012, the Food and Drug Administration approved the combination of pertuzumab with trastuzumab and docetaxel as first-line treatment of HER2-positive metastatic breast cancer. Furthermore, pertuzumab is the first drug to be approved in the neoadjuvant setting using a pathological complete response as an endpoint. Areas covered: The review provides insights into the main mechanisms of action of pertuzumab...

In an operant serial feature-positive procedure, an occasion setter (OSX) signals that a response will be reinforced in the presence of a second stimulus (e.g., a discriminative stimulus, A). During a transfer test, the OS is paired with a different discriminative stimulus. Experiment 1a tested transfer effects in a touchscreen-based spatial occasion setting task with pigeons. During training, four OSs (OSW, OSX, OSY, and OSZ) were paired on separate trials with landmark A (LMA) or B (LMB) and the opportunity for a reinforced response at one location to the immediate left (R1) or right (R2) of the LM (OSW→LMA:R1, OSX→LMA:R2, OSY→LMB:R1, OSZ→LMB:R2)...

Several landmark trials have assessed the effects of aggressive hypertension control on the progression of nondiabetic chronic kidney disease. Results generally have been disappointing. With the realization that lowering blood pressure, including with renin-angiotensin system blockade, failed to reliably prevent end-stage kidney disease, studies now are analyzing longer-term effects of hypertension control on survival in chronic kidney disease. This commentary reviews the current findings and extends the discussion to apolipoprotein L1 gene by blood pressure (or gene by environment) interactions...

Automated phenotyping is essential for the creation of large, highly standardized datasets from anatomical imaging data. Such datasets can support large-scale studies of complex traits or clinical studies related to precision medicine or clinical trials. We have developed a method that generates three-dimensional landmark data that meet the requirements of standard geometric morphometric analyses. The method is robust and can be implemented without high-performance computing resources. We validated the method using both direct comparison to manual landmarking on the same individuals and also analyses of the variation patterns and outlier patterns in a large dataset of automated and manual landmark data...

BACKGROUND: Although survival analyses represent one of the cornerstones in oncology in general, some aspects of the reported survival data in lung cancer patients are still not fully elucidated. METHODS: After having defined several open questions, an evidence based approach was applied in order to answer these questions. Areas of interest were: (I) possible uncertainties in reported survival data; (II) survival surrogates; (III) recommended methods for evaluating progression free survival (PFS) as a surrogate endpoint in future datasets; (IV) postoperative lung cancer recurrence and survival...
